In November 2009, Talecris Biotherapeutics announced an ambitious US$269 million expansion of its Clayton, NC, manufacturing facility. The company was subsequently purchased by Grifols, Inc. in 2011. Constructing a new facility with a state-of-the-art manufacturing process intended to generate clinical products involves top-notch project management, exceptional fortitude, and numerous supply chain decisions. Suppliers are often relied on to provide standard product support. When used effectively, they can be an invaluable resource beyond basic services. Additional support may include…
MAb
Toward Nonantibody Platforms
Monoclonal antibodies (MAbs) remain the largest segment of the biopharmaceutical market, but they are not the only recombinant proteins in development. Remember that the first biopharmaceutical approved for sale was recombinant insulin — a hormone — back in the 1980s. And proteins aren’t the only recombinant biologics. The sector has expanded since then to include gene therapies and viral vectors, vaccines, and even cells and tissues. Companies around the world are developing such products for cancer, neurological, infectious disease, metabolic,…
Carrier Protein Outsourcing
Vaccines represent a significant, increasing area of product development within the biopharmaceutical industry. The segment includes several blockbuster commercial products, nearly 300 vaccines currently in development, and many more candidates in various stages of research and preclinical development (1). The 2010 worldwide vaccine market was ~US$20 billion and is projected to approach $30 billion by 2015 (2). Conjugate vaccines sales currently exceed $7 billion and are expected to increase substantially. Conjugate vaccines (covalently linked polysaccharide and protein) have…
Production of a Viral-Vectored Vaccine Candidate Against Tuberculosis
Vaccines are among the most efficacious and cost-effective human health interventions available. They provide protection against a surprisingly broad spectrum of infectious diseases. Notable recent successes protect against human papillomavirus (Cervarix and Gardasil vaccines from GlaxoSmithKline and Merck, respectively) and rotavirus (Rotarix and RotaTeq vaccines from GlaxoSmithKline and Merck, respectively). However, generating reliable sterilizing or therapeutic immunity is still not possible against a number of latent and chronic pathogens that especially affect people in developing countries. Among those…
Vertical Integration of Disposables in Biopharmaceutical Drug Substance Manufacturing
Single-use (disposable) technologies are gaining significant traction in biopharmaceutical manufacturing due to reductions in capital investment for plant construction, lower requirements for cleaning and sterilization, and the advantages of eliminating cross-contamination during multiproduct manufacturing (1,2,3,4). In the early days of disposables, single-use (SU) systems were used only in specific unit operations (5, 6). Recently, however, options have become more widely available throughout drug-substance manufacturing (7,8,9,10). Companies now focus on selecting the right SU technology from an array of…
Implementing a Fully Disposable MAb Manufacturing Facility
Biopharmaceutical contract services have seen some very important changes and growth in recent years, part of an increasing trend toward outsourcing by pharmaceutical companies both large and small. And we have seen a significant change in the types of services demanded by clients. In addition to typical services such as validation, analytical services, and training, for example, demand has increased for outsourcing of process development, mammalian cell culture, good manufacturing practice (GMP) production, and final formulation and filling.…
Outlooks on Standardization
The Friday workshop of the 2011 BPI Conference in November may have been titled “Industrialization of Single-Use Manufacturing Technologies,†but in the discussion afterward, the mainly end-user audience zeroed in on an on-going debate in single-use implementation: standardization. Comments and questions echoed the current opinions, most of which were well known to the all-supplier panel and others present. To follow up on this discussion, I spoke with members of that panel because — as one expert put it…
The Maturation of Single-Use Applications
“Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.†—Albert Einstein Single-use systems (SUSs) have been treated as novel technologies for some time. I have spent much of the past 10 years introducing clients to SUSs and integrating them into conventional processes. They are part of the biopharmaceutical development and production landscape and a mature, integrated option for bioprocessing. The value of SUS integration is soundly substantiated: reduced cross-contamination risk…
Single-Use Technology Supports Follow-On Biologics
Follow-on biologics (FOBs, or biosimilars) differ from generic small-molecule compounds and pioneer biopharmaceuticals in several ways. Those differences affect aspects of their regulatory approval pathway, analytics, and marketing (1). Many biological active pharmaceutical ingredients (APIs) are actually incompletely characterized dynamic mixtures of macromolecules with slightly different primary compositions or higher-order structure (microheterogeneity). Those properties of macromolecules (unlike small molecules) are greatly influenced by their individual manufacturing process. Emerging regulatory guidelines for follow-on biologics are clarifying aspects of their…
Implementing Custom Single-Use Solutions for Cell Therapy Production
Cellular therapy continues to expand and gain momentum, as evidenced by the growing number of companies and clinical trials in the field each year. Early potential therapies were developed solely by investigators without communication or input from manufacturing experts. That communication gap led to numerous setbacks as potential products were developed without roadmaps for feasible manufacturing scale-up (or scale-out). Contributions from members of the cell therapy community over the past few years have significantly improved the situation in the form…
